Thank you Axel. Your advise rises another doubt. Can we get the maximum
performance from a highly clocked CPU?
I used to consider that the the fastest CPUs were too fast for the memory
access, resulting in bottlenecks. Of couse it depends on cache size.

than the maximum >number of cpu cores and a higher clock instead.
